Conventionally, this type of small inductor has been manufactured as follows, using a toroidal ferrite core as an example. A coated wire is wound around a toroidal core to form an inductor element, and terminal treatments such as peeling off the coating and solder plating are performed at the ends of the coated wire. Next, the terminal processing part is attached to the lead terminal part, the lead terminal part is connected using a soldering method, and the entire inductor element is molded and exteriorized with insulating resin, leaving a part of the lead terminal part.

In the manufacturing method described above, during mold exterior work,
Due to the injection pressure of the molding resin, the inductor element tends to move into the mold, making it difficult to determine its position. For this reason, the soldered joints of the covered wires are sometimes prone to breakage due to the injection pressure, resulting in a disadvantage that the product lacks reliability.

となり量産には不適であつた。 Also, regarding workability, when connecting the inductor element's coated wire to the lead terminal, the end of the coated wire must be treated in advance by stripping the coating and soldering, and then connected using the soldering method. Terminal processing is required, which requires a large number of man-hours. Furthermore, the inductor element is not fixed during the soldering process, making the process of soldering the winding leads cumbersome and unsuitable for mass production.
